"Sawdah feared that the Prophet ﷺ was going to divorce her, so she said: 'Do not divorce me, but keep me and give my day to 'Aishah.' So he ﷺ did so, and the following was revealed: Then there is no sin on them both if they make terms of peace between themselves, and making peace is better (4:128). So whatever they agree to make peace in something then it is permissible."  

أَنْ يُطَلِّقَهَا النَّبِيُّ ﷺ فَقَالَتْ لاَ تُطَلِّقْنِي وَأَمْسِكْنِي وَاجْعَلْ يَوْمِي لِعَائِشَةَ فَفَعَلَ فَنَزَلَتْ ( فَلاَ جُنَاحَ عَلَيْهِمَا أَنْ يُصْلِحَا بَيْنَهُمَا صُلْحًا وَالصُّلْحُ خَيْرٌ ) فَمَا اصْطَلَحَا عَلَيْهِ مِنْ شَيْءٍ فَهُوَ جَائِزٌ كَأَنَّهُ مِنْ قَوْلِ ابْنِ عَبَّاسٍ  

[Machine] It was reported that the Prophet ﷺ divorced her, so she said, "O Messenger of Allah, do not divorce me, hold on to me, and make my day for Aisha." So he did as she requested, and then this verse was revealed: "And if a woman fears from her husband contempt or evasion, there is no sin upon them if they make terms of settlement between them" [Quran 4:128]. He said, "Whatever they agree upon is permissible."  

يُطَلِّقَهَا رَسُولُ اللهِ ﷺ فَقَالَتْ يَا رَسُولَ اللهِ لَا تُطَلِّقْنِي وَأَمْسِكْنِي وَاجْعَلْ يَوْمِي لِعَائِشَةَ فَفَعَلَ فَنَزَلَتْ هَذِهِ الْآيَةُ {وَإِنِ امْرَأَةٌ خَافَتْ مِنْ بَعْلِهَا نُشُوزًا أَوْ إِعْرَاضًا} [النساء 128] قَالَ فَمَا اصْطَلَحَا عَلَيْهِ مِنْ شَيْءٍ فَهُوَ جَائِزٌ
